Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile devices are used to communicate with industrial apparatuses, then operator productivity and notification delivery are improved, but access control and interference prevention become problematic
Solution Approach 1:
A communication server acts as an intermediary between mobile devices and industrial apparatuses. The server manages communication connections, assigns unique labels to pair devices with apparatuses, and controls access based on shift schedules. This intermediary structure enables multiple operators to use mobile devices productively while maintaining reliable access control and preventing interference.
Solution Approach 2:
The system segments access control by creating unique communication connections for each operator-apparatus pair through label assignment. Each mobile device receives a specific label that identifies its authorized industrial apparatus, dividing the overall system into discrete, controlled communication channels. This segmentation prevents interference while maintaining high productivity.
2Productivity
If multiple operators use mobile devices simultaneously, then operational efficiency is improved, but unintentional interference and unauthorized access increase
Solution Approach 1:
The communication server mediates all interactions between multiple operators and industrial apparatuses. It assigns unique labels to each operator-apparatus connection and enforces shift-based access control, allowing multiple operators to work efficiently simultaneously while preventing unintentional interference through structured management of communication channels.
Solution Approach 2:
The system changes the parameter of access control by implementing time-based restrictions through shift schedules. Access rights are dynamically adjusted based on the operator's current shift status, enabling multiple operators to efficiently access different apparatuses at different times while preventing interference during overlapping periods.
3Reliability
If constant assignment of machines to operators is implemented, then operational reliability is improved, but flexibility in operator availability decreases
Solution Approach 1:
The system implements dynamic assignment where mobile devices are assigned to industrial apparatuses based on current shift schedules rather than fixed permanent pairings. The communication server continuously manages label assignments and access rights, allowing operators to be reliably connected to apparatuses during their active shifts while maintaining flexibility to adapt to changing availability and operational requirements.
